Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry humidifier using a solid adsorbent.

[0002]

2. Description of the Related Art A conventional dry humidifier, for example, a rotary dry humidifier, can be rotated by providing a cylindrical solid adsorbent in an annular casing as described in JP-A-63-286634. The inside of the casing is divided into an adsorption section and a desorption section, and the outdoor air is blown to the adsorption section to adsorb the moisture to the solid adsorbent, and when the room is humidified, the solid adsorbent that adsorbs the moisture is desorbed. The air in the room is heated to the desorption part while being rotated to the part to be circulated by blowing air, and the humid air containing the water desorbed from the solid adsorbent is blown into the room to humidify it.

FIG. 10 shows the outline of the function of the rotary type dry humidifier disclosed in Japanese Patent Laid-Open No. 63-286634, in which a solid adsorbent made of honeycomb silica gel containing lithium chloride is contained. The suction rotor 1 is provided in an annular casing (not shown) made of resin or metal. The inside of the casing is also separated by a partition wall 2 into an adsorption section 3 and a desorption section 4, and the adsorption rotor 1 is slowly rotated by a drive motor 5 equipped with a rotation mechanism such as a belt to adsorb the solid adsorbent inside the adsorption rotor 1. It moves from the part 3 to the desorption part 4 and from the desorption part 4 to the adsorption part 3.

When the adsorption blower 6 is driven to suck the outdoor air into the adsorption portion 3, the moisture in the outdoor air is adsorbed by the solid adsorbent. When you want to humidify the indoor air, the adsorption rotor 1
Is rotated to move the solid adsorbent in the adsorption unit 3 to the desorption unit 4,
When the desorption blower 7 is driven while the indoor air is being heated by the heater 8 and sucked into the desorption unit 4, the moisture of the outdoor air adsorbed by the solid adsorbent is desorbed and discharged into the room. If this operation is performed while slowly rotating the adsorption rotor 1 by the drive motor 5, the moisture in the outdoor air continues to humidify the indoor air through the solid adsorbent.

[0005]

However, when this dry humidifying device is installed outdoors, in order to suck indoor air into the humidifying device or discharge humidified air into the room to circulate it, the space between the indoor and the outdoor is to be improved. It is necessary to install an air duct in.
In order to reduce the pressure loss when circulating the indoor air, it is necessary to make the air duct relatively large, and the blower also becomes large and the device becomes large. In addition, noise is generated when air is circulated in the air duct. Further, since the heated and humidified moist air may cause dew condensation inside the air duct due to a temperature difference between the inside and outside of the air duct, it is necessary to cover the air duct with a heat insulating material.

An object of the present invention is to provide a dry humidifying device which solves these problems.

[0007]

According to the dry humidifier of the present invention, an adsorption rotor containing a solid adsorbent is provided in an annular casing made of resin or metal, and the inside of the casing is divided by a partition into an adsorption portion and a desorption portion. Drive motor equipped with a rotation mechanism such as a belt for rotating the adsorption rotor, a suction fan for sucking outdoor air into the adsorption section, and outdoor moisture adsorbed by the solid adsorbent to the outdoor For desorption with air, a desorption blower that inhales and heats outdoor air to the desorption part and a heater for heating, and for cooling the dehumidified moist air containing moisture to obtain dew condensation water. A dew condenser, a water pipe for introducing dew condensation water into the room, an evaporation tray for evaporating the dew condensation water introduced as a humidifying means in the room, and an evaporation heater are provided.

[0008]

According to the present invention having the above structure, when the adsorption blower is driven to suck the outdoor air into the adsorption portion, the moisture of the outdoor air is adsorbed by the solid adsorbent of the adsorption rotor. When the desorption blower is driven and the outdoor air is heated by the heater for heating and sucked into the desorption section, the moisture of the solid adsorbent is desorbed. Further, the moist air containing the desorbed water flows into the dew condensation machine to form dew condensation at the dew condensation section cooled by the cooling fan, and the dew condensation water drops and enters the water passage pipe and flows down to the evaporation tray in the room due to the height difference. . Since the evaporation tray is heated by the evaporation heater, the dew condensation water that has flowed down evaporates there and humidifies the room. Since these operations are performed while the adsorption rotor is slowly rotated by the drive motor, the air in the room is continuously humidified.

Adsorption rotor 1 loaded with 0% and silica gel 50%
And

A partition wall 2 for separating the adsorption section 3 and the desorption section 4
Is based on the relationship between the adsorption efficiency that depends on the temperature of the outdoor air and the desorption efficiency that depends on the rising temperature of the indoor air that is heated for desorption. Is set to 1. Since the adsorption rotor 1 has a cylindrical shape, the partition wall 2 opens at an angle of 90 ° with respect to the rotation axis of the adsorption rotor 1 to divide the inside of the casing.

When outdoor air having a flow rate of 81 m ³ / h is sucked into the adsorption section 3 by the adsorption blower 6, the moisture of the outdoor air is mainly adsorbed by silica gel which is a solid adsorbent. When the adsorption rotor 1 is rotationally moved to the desorption unit 4, the adsorbed moisture is about 1 by the desorption blower 7 for heating the outdoor air by the heater 8.
When heated to 00 ° C and sucked into the desorption unit 4 at a flow rate of 27 m ³ / h, the moisture of silica gel is desorbed and the outdoor air is about 5
It becomes humid air at 0 ° C. Next, since this moist air flows into the dew condensation device 9, the moisture in the moist air is condensed and removed, and the remaining air is discharged to the outside of the room. The dew condensation water of the dew condensation device 9 drips and flows into the water passage pipe 10 and is introduced into the room by utilizing the height difference, flows down into the evaporation tray 11 and is heated by the evaporation heater 12 to evaporate and humidify the room.

The condensed water drops on the water pipe 10 and flows down from the outside to the indoor evaporation tray 11 through the water pipe 10 due to the height difference. Since the evaporation tray 11 is heated by the evaporation heater 12, the condensed water evaporates and humidifies the room.

In the above operation, the suction rotor 1 is moved to 1 hour per hour by the drive motor 5 having a rotation drive mechanism such as a belt.
Since it is carried out while rotating at a slow rotation speed of 2 to 14 rotations, the dew condensation water obtained by desorbing water by adsorbing moisture from the outdoor air and heating the outdoor air and obtained by the dew condensation device 9 is introduced into the room and evaporated. Humidification is continuous.

Thus, a rotary flow is generated in the moist air to prolong the residence time and more efficiently the condensed water can be obtained.

FIG. 7 is a sectional view in the axial direction of FIG. 6, in which the moist air duct 92 is inclined with respect to the horizontal plane, and the condensed water dropped in the condensed water receiving groove 98 easily flows due to the height difference. There is.
